High frequency QR-Flyback design: Design up to 500kHz,100W,300-1000Vdc wide input range QR-flyback to minimize the whole product size and in the meantime to find our high voltage SiC Mosfet's limit in such frequency; Applying the special/brandnew SiC driver and QR-high frequency controller into this design; Layout and Magnetic transformer are totally different comparing the traditional Flyback converter; Loop design: small signal analysis Achieved high efficiency under high switching frequency. Shared the product design in Semicon Europa.

Reference Design: 1. High power module (1200V/100A Press-fit) optimize the application and provide a super easy way to apply our module in customer's system; Low inductance; Flexible driver solutions; integrated wirelaid tech into the design for high current application. 2. 48V/300A 3-phase Half-bridge Motor driver: succeed in design high power density motor driver in round shape board; super creative symmetric for current distribution and driver loop; low inductance design; Easy use for the customer; 3. Wild-bandgap Product(SiC/GaN): Benchmark/double -pulse-testing; Design the special driver board for testing the new device and provide technical results to our device engineer in improving the performance.
